ROTARY-ENGINE REVERSING- GEAR.

SPECIFICATION forming part of Letters Patent No. 395,646, dated January1, 18189. Application filed February 8,1888. Serial No. 263,328. (Nomodel.)

To to whom it may concern.-

Be it known that I, OYRUs BAILEY, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Rotary-EngineReversing-Gear; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention consists in the improved con struction of a rotary engineand reversinggear for the same, hereinafter to be described.

In the drawings, Figure 1 shows an end view of the engine with the leverfor operating the reversing-gear. Fig. 2 is an inclined. axial sectionof the same on line 2 2, Fig. 3. Fig. 3 is a vertical cross-section ofthe engine, taken on the line 3 of Fig. 2. Fig. 4 is a section taken. onthe line 4 4: of Fig. 2, show ing the end of the crank-cylinder with thereversing-valve mounted on the same. Fig. 5 is a horizontal, axial.section of the enginebearing, showing in detail the apparatus forcontrolling the reversing-valve. Fig. 6 is a vertical moss-section takenon the line 6 (i of Fig. 5. Figs. 7 and 8 show the reversingvalve incross and longitudinal sections.

Throughout the drawings like letters refer to like parts.

The construction of my improved engine, as illustrated in the drawings,is as follows:

A is the standard and easing of the engine, cast in one piece.

A is the face-plate, bolted onto the part A, as shown in Fig. 2, andthus inclosing the entire mechanism.

B is the crank-disk, mounted on the shaft (1, which runs within thebushing d, mounted in the casing A. The packing-gland 0 enables thejoint about the crank-shaft to be so packed as to prevent the escape ofany steam which may work between the bearingsurfaces. To the crank-diskB are bolted the cylindrical piece B and the plate B". constitute what Icall the crank-cylinder. The plate 3 is extended in the form of acylindrical thimble, which is represented by the letter F in Fig. Thisfits over and revolves upon a projecting boss, f, formed on theface-plate A, which furnishes an additional bearing for thecrank-cylinder in line lating packing-piece X.

parts E, D ,and X are arranged in the other These togetherwith thecrank-shaft (Z. \Vithin the crankcylinder is a partition, V, dividing itinto two parts, as clearly shown in Fig. 2. In one part is mounted thepiston E and the rotary packing-cylinder D. Steam-tight connectionbetween these two parts is afforded by the oscil- In the same waychamber. The rotary packing-cylinders D and D are provided on theirfaces with packing-rings 1'), as shown most clearly in Fig. 2. Therotary cylinder I) is also provided with an extended cylindrical boss,0, on which its companion cylinder D is j ournaled. The cylinder D inits turn is journaled upon the eccei'itric-stinl C, which has a taperedbearing in the face-plate A.

Steam enters the engine through the inletpipe I and is delivered to thesteam-space 2'. (Best shown in Fig. 4.) From this it passes at properintervals through the openings Z Z in the projecting boss F to thepassages g g in the adjustable reversing-valve, and through the passagesh It and R R in the plate Bto the steam-ports 0'51", opening into thespaces behind the pistons E E.

The valve G, having the passages g g, is circumferentially adjustable onthe boss F and revolves with the crank-cylinder. Its adjustment uponthat boss is fixed in the following manner: In the projectingthimblelike part of the valve G are two oblique slots, M and M, as shownin Figs. 5, 6, and 8. In the part F are corresponding axial slots.Mounted upon the valve G is the ring O,having projecting pins S S and agroove, '0. These pins pass completely through the slots M M and intothe slots T T in the parts F. It is evident, therefore, that theadjustment of the ring 0 along theline of the axis of the crank-cylinderwill throw the valve G to one side or the other so that its ports 9 willregister with the passages 71 h or the corresponding set of passages, 107a.

The motion of the ring 0 may be controlled in a variety of ways. Mypreferred construction is that shown in Figs. 2, 5, and 6. Reg isteringwith the groove 0 are projections 0 and 0 on sliding pieces N N, whichare mounted in the projecting boss f of the faceplate A. Packing glands25 t prevent the leaking of any steam which may work be tween the partsof the engine, and also guide the pieces N N. To these latter arepivoted by the pins K K links m m, which are in turn connected to thetwo branching arms a n of the lever L. This lever is pivoted by the pinq to the bracket Q. It is evident, therefore, that a to-and-fro motionof the lever Ii willreverse the engine.

The object of the eccentric-stud O, previously described, is to affordmeans for taking up the wear of the rotary packing-cylinders D D. \Yhenthis is to be done, the nut Uis loosened, the stud turned by a wrenchplaced 011 its squared end a, and then again drawi'i tightly into itstapered bearing by setting up the nut U.

The operation of my engine may be briefly set out as follows: Steam isadmitted at the inlet-pipe I, and, passing to the steam-space 1', isfrom thence distributed to either or both of the chambers in theerank-cyliiuler, accord in g as either or both of the openin Z Z are inconnection with said steam-space t. It is evident that each of saidopenings will be in such connect-ion during about three-quarters of therevolution with the proportion of parts shown in Fig. 4. The position ofthe valve G determines whether the steam passing through the openings ZZ shall be conducted through the ports h h or to the opposing set, is k.I11 the state of affairs illustrated in the drawings the valve Gregisters with the ports h h, and the steam is admitted behind thepistons E E when the engine is .rotated in the direction of the hands ofa watch if looked at as in Figs. 1, 3, 4:, and 6. The exhauststeam 011the other side of the pistons E E is allowed to escape continuouslythrough the ports and passages terminating at. the ports 1.: into theexhaust-chamber,lV, which almost entirely surrounds the crank-cylinderand from which the exhaust-steam escapes through the passage Y. (Shownin Fig. 2.)

The general construction and principle of operation of my engine havebeen fully set out in my application filed September 27, 1886, SerialNo. 214,616, and to such I make no claim in this application.
